Sigma state at various places if lenses are Sony/Minolta compatible. That reference to Minolta implies the lenses are A-mount. Tamron aren't so forthcoming but if they say "Sony" then assume A-mount. Zeiss say "Alpha bayonet" for their normal third party lenses but, of course, Sony also directly sell a Zeiss branded E-mount lens. There's nothing that I'm aware of to stop you using any A-mount lenses on a NEX via an adaptor though I think you'd have to check to see if there were any functional restrictions. Samyang have produced an E-mount fish-eye.

It's ironic that Sony have arguably produced the compact system camera by which all others may be judged (the NEX-7, although it has been delayed due to the floods) but there are still a lot of gaps in the E-mount lens line-up. Maybe the Carl Zeiss® Sonnar 24mm f/1.8 is a sign that there is more to come. I certainly hope so.

The adapter is expensive heavy and only the adapter with the reflex mirror which is large & heavy has full functions plus a super focus system.The sony reflex lenses are of course,for the NEX,bulky heavy and costly

It would be far better for me to buy the 18-55mm or the huge 18-200 if it were available

I ordered the new 30mm f1:8 i think which would have been a good lens for me,i just checked the delivry date which still says end september?

Has the sony lense production plant been flooded?? I havnt read anything about flooding nor production delays.

The NEX is good,i just hope Sony dosnt find out or the price will remain high,

A few days ago on a Russian metro line holding on with one hand with the other i changed the asa white balance and spot focusing took an image,the a seires,

By chance there was another tourist just behind me with a family & Nikon D300 he was amazed at the flexability of my tiny point & shoot
